Answer: Kahn is wrong because the sequence increases by 5 after every number. The next two numbers in the sequence would be 28, 33. Kahn puts 29, 33 which is incorrect.

Answer:

He was supposed to put 28 instead of 19

Step-by-step explanation:

He started at 8 and then kept counting by 5's but then when he got at 23 he counted 6 times instead of 5 which got him 29. If he would have kept counting by 5's he would have gotten 28 instead of 29.

A:B=3:4 and B:C =7:2 then find A:C? *

Mazyrski [523]

Answer:

21 : 8

Step-by-step explanation:

A:B=3:4

A/B = 3/4

A = 3/4 B..... (1)

B:C =7:2

B/C = 7/2

B = 7/2 C.... (2)

From equations (1) & (2)

$A = \frac{3}{4} \times \frac{7}{2} C \\ \\ A = \frac{21}{8} \\ \\ \frac{A}{C} = \frac{21}{8} \\ \\ A :C = 21 : 8$

Which matrix is equal to... (picture added)

Ghella [55]

Answer:

D $\left[\begin{array}{ccc}-6&-6.5&1.7\\-2&-8.5&19.3\end{array}\right]$

Step-by-step explanation:

Two matrices are equal when they

have the same sizes (so options A and B are false)
have equal corresponding elements (so option C is false, because -6≠6, -6.5≠6.5, 1.7≠-1.7 and so on)

If in option D the second row is 2 -8.5 19.3 , then these matrix is equal to the given.
